Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Generally, a patio is more accessible than a standard deck because patios are constructed at ground level. However, decks can be made accessible by adding a wheelchair-accessible ramp, a vertical lift, or a stair lift along the entry. An ADA-compliant deck ramp costs about $3,000 on average. The additional investment will provide a much friendlier experience for your guests with movement impairments.

Before installing any materials under the deck for removing moisture, you should perform some prep work on the ground. Work the dirt under the deck to create a grade away from the home. A grade of at least six inches for every 10 feet works well. Do not leave a gap between the dirt and the home’s foundation where water could pool. Once you or a contractor regrades the dirt under the deck, you then can add materials over the top.
